Kathy, According to my records, in 1729, Philemon Kavanaugh, Sr. was ordered by the court to do an inventory of property owned by Charles Kavanaugh, Sr.in 1729.The reason he was ordered to do this is that Charles was only about 6 to 8 years old at the time and could not do it for him self.Apparently Philemon, Sr. patented land for his young son.It was not necessary for the person to be 21 to patent land.Charles was probable born about 1721 because he was 21 or over when his father made his will 9 Apr 1743 listing him as one of the excutors.Another clue to his young age is that his father mentions in his will, "if he has begotten children", which to me means that he is married but has no children or not yet married. I think, (key word"think") that Charles, Sr. was the first child of Sarah (Williams)Kavanaugh. There seems to be about 5 or 6 years between the birth of Jael Kavanaugh who married Thomas Covington and Charles, Sr. which makes it possible that Philemon, Sr. was married before he married Sarah,however, if Sarah was born 1695 and was 18 in 1713 when Winifred was born then she would be 48 when William was born in 1744.Possible but not probable.There is the problem of the name Jael, which comes from Sarah's line.There seems to be no clear answer yet. I finally found the answer to a line I have searched for for 30 years so lets not give up on the answers we are searching for. My email address is email@example.com. Please feel free to use it.Bettye.
